Technical Details & Test Data
- Processing
Pre-expansion
With discontinuously operating, state-of-the-art preexpanders sunpor® A415 can be preexpanded in one step to densities of approx. 12 kg/m³. Lower densities can be achieved by double preexpansion or in optimized machines. sunpor® A415 has been treated with an antistatic agent to prevent a build up of electrostatic charge during transport of the expanded beads.
Intermediate aging
Intermediate aging should be between 10 and 48 hours. Higher-density material may easily be processed after a longer time interval without adversely affecting quality.
Molding:
sunpor® A415 can be processed in industry-standard block molds and shape molding machines. The material allows the production of a wide range of molded parts and, by varying the steaming and filling gap parameters, the degree of fusion and the surface structure can be optimized for specific applications. Good mold-filling properties are achieved with minimum wall thicknesses of approx. 8 mm.
Safety & Health
- Safety Instructions
Flammable pentane-air mixtures may be generated during storage and processing of sunpor® A415. For this reason, adequate ventilation must be ensured (LEL pentane 1.3 % by volume). The blowing agent pentane escapes relatively slowly from EPS foam blocks. Thus, when cutting recently molded blocks, the formation of a flammable pentane-air mixture has to be anticipated. In addition, all conceivable sources of ignition must be kept away, and the build-up of electric charges has to be prevented.
Packaging & Availability
- Packaging
sunpor® A415 is shipped in octabins (height max. 192 cm) on wooden pallets (114 x 114 cm) containing 1,150 kg net of material.
- Shipping
UN-Number 2211 Designation Polymeric beads, expandable
Class 9 Packing Group III ADR
Storage & Handling
- Storage
The octabins are not weather- or water-proof and must therefore not be exposed to outdoor conditions. It is not recommended to stack octabins more than one layer high. In case of double-stacking octabins under controlled conditions, the recommendations laid out in the document "Instructions for stacking sunpor octabins“ must be followed.
In order to obtain the desired properties of sunpor®A415, the raw material should be stored below 20 °C and be processed within one month.
